Why is this study being done?

The PI on this proposal has been studying BEST1 and the protein encoded (Best1) since its discovery in 1998. Best1 is an integral membrane protein that in the eye is expressed only by retinal pigment epithelial (RPE) cells where it is localized to the basolateral plasma membrane. Methods: Once a subject has been identified as a potential candidate, a study coordinator will meet with the subject, to discuss the study prior to sample collection. The study coordinator will review the consent form with the subject and spend as much time as necessary answering any questions. Once the subject has signed the consent form, study procedures will begin. Following the consent process, a skin sample will be obtained from subjects using a (4mm) dermal punch biopsy method. This will be accomplished in a single visit to the Regenerative Medicine Consult Service or other approved clinical examination room. A suture may need to be placed following this skin biopsy. A health care provider (either at Mayo Clinic or a local health care provider's office) can remove the stitches, or the subject can remove them with a provided disposable suture removal kit. Subjects will also be asked to undergo venipuncture; all subjects will be asked to have the venipuncture and have the option to refuse. 10ml of blood will be collected for RNA and DNA extraction. Once the skin biopsy is obtained,skin fibroblasts will be isolated, which will be reprogrammed into iPSCs. RPE cells will be derived from the iPSCs. Remuneration: If subjects make a special trip only for the research procedures, they may be reimbursed for travel expenses including: airfare, mileage, parking, and hotel. In order to receive reimbursement, they must provide a copy of the original receipts for those expenses. Reimbursement will not exceed $1000.00.

Who is eligible to participate?

Inclusion Criteria: - Patient must have been diagnosed on the basis of genotyping with a bestrophinopathy. - Patient must be willing to provide a skin biopsy from which we will generate ipSCs. - For pediatric patients, parents must be willing to donate skin biopsies as well. Exclusion Criteria: - Children under the age of 5 - Patients exhibiting secondary ophthalmic disorders that are not typically associated with the bestrophinopathies may be excluded. - Pregnant women
